Abstract
Systems and methods recycle liquid(s) by introducing at least a portion of a first liquid from a first centrifuge into a tank. At least a portion of a second liquid is introduced from a second centrifuge into the tank. The first liquid and the second liquid are mixed together in the tank to produce a mixed liquid. At least a portion of the mixed liquid is introduced from the tank into the second centrifuge. Particles from the mixed liquid are separated using the second centrifuge, thereby producing the at least a portion of the second liquid that is introduced from the second centrifuge into the tank.
Claims19
A method comprising:
- partitioning an internal volume of a tank into a first portion, a second portion and a third portion, wherein the third portion is provided between the first and second portions;
- introducing at least a first portion of a first liquid from a first centrifuge into the first portion of the internal volume of the tank;
- introducing at least a first portion of a second liquid from a second centrifuge into the second portion of the internal volume of the tank;
- directing the first portion of the first liquid and the first portion of the second liquid to flow into the third portion of the internal volume of the tank, wherein a surface, oriented at an angle with respect to a central longitudinal axis through the tank, deflects the first portion of the first liquid to flow into the third portion of the internal volume and the angle is from about 10 degrees to about 80 degrees;
- mixing the first portion of the first liquid and the first portion of the second liquid together in the third portion of the internal volume of the tank to produce a mixed liquid;
- introducing at least a first portion of the mixed liquid from the tank into the second centrifuge;
- and
- separating a plurality of particles from the first portion of the mixed liquid using the second centrifuge, thereby producing at least a second portion of the second liquid that is introduced from the second centrifuge into the tank.

A system for recycling a liquid, comprising:
- a first centrifuge;
- a second centrifuge;
- and
- a tank comprising:
- a first partition provided in an internal volume of the tank;
- at least one second partition provided in the internal volume of the tank such that the internal volume of the tank is partitioned into a first portion, an opposite second portion and a third portion between the first and second portions;
- a first inlet adjacent to the first portion of the internal volume and configured to receive a first liquid from the first centrifuge;
- a second inlet adjacent to the second portion of the internal volume and configured to receive at least a first portion of a second liquid from the second centrifuge;
- a side wall of the tank or a portion of the first partition, oriented at an angle with respect to a central longitudinal axis through the tank, configured for deflecting or directing the first liquid received from the first centrifuge to flow into the third portion of the internal volume of the tank, wherein the first liquid and the first portion of the second liquid mix together in the third portion of the internal volume of the tank to produce a mixed liquid and the angle is from about 10 degrees to about 80 degrees;
- and
- a first outlet configured to output at least a first portion of the mixed liquid to the second centrifuge, wherein the second centrifuge is configured to separate a plurality of particles from the first portion of the mixed liquid, thereby producing a second portion of the second liquid that is introduced from the second centrifuge into the tank.
